IMPROVEMENT IN IN HALATOPLS.

Specification forming part of Letters Patent No. 43,536, dated July12,1864;

patented in England and France May 10, 1864.

To all whom it may concern:

Be it known that I, MAURICE VERGNEs, of the city, county, and State ofNew York, have invented a new and useful improvement in the apparatusdestined to introduce medical substances into the lungs and throat byinhalation; and I hereby declare that the following is a full and exactdescription thereof.

Having noticed the difficulty of conveying by vapor the salts and heavysubstances to the cavities ot' the lungs, 85e., in eases of phthisis, Ihave planned this apparatus, by which I can convey them in apulverulentstate.

To enable others skilled in the business to makeand use my invention, Iproceed to describe its construction and operation, reference being hadto the drawings hereunto annexed and making part of this specification.

Figure l represents the apparatus upon a table, the attitudel of aperson using it for inhaling the prepared powders; Fig. 2, the box withcover thrown open; Fig. 3, section showing the inner box, D, with thebottom of it semicircular and with the revolving brush or fan; Fig. 4,edge view of the box; Fig. 5, the sieve connected with the cover fordiffusing the powders 'that rise before they can be inhaled.

rlhe same letters refer tothe saine things in all the drafts.

A represents the box or whole exterior of the apparatus;B,thepersoninhaling; C,theopen ing to which the mouth is applied whileusing it, and which is thus closed; D, an interior box, generally oftin, (the bottom is semi-cylindrical, to lit the sweep of the rotary fanE, an opening at one side of the tin case D, to admit the air which isdrawn in by the rotation of the fan; F, the outside apertures admittingair; G, the cover or roof part of the box; H, the wings of the fan, madeof hair or feathers, or any light substance; I, the sieve, which is setin the bottom part of the cover G to diffuse the rising powders, which,as the breath is drawn, come up through the sieve with the air.

The shape .or construction of the exterior box, A, is not essential. Itis to inclose properly the inner box, D, and the sieve I. The box D ismade to take in or out at will for cleansing. The revolving fan is alsomade to take in or out, to be cleaned, or when different preparationsare to be used. The crank therefore requires to be connected with theinner box and fan by a screw-shank, to be screwed into place after thebox D and its revolving fan are putin. One end of the shaft or cylinderto which the wings H are attached has a journal or pivot. p

The fan may be made with few or many wings and these constructed ofhair, feathers, or any light substance. To put this to use, the top orcover is opened and the pow ders putin. rIhe medicated powders should bepulverized to the highest degree and superdesiccated, and be keptbottled and safe from the absorption of water from the air. When theseare put in, the cover is shut down and the person who uses them sitsbefore the box, as shown, Fig. 1, and, placing the mout-h and nose inthe opening (l, so as to close it, turns the crank with more or lessspeed, according to the nature of thepowders, to disturb them and infusethem in the air, at the same time drawing in the breath. rIhe expirationof breath may be out ofthe box or within it; but out of it is best. Bythe inhalation the air comes in at the opening E, made in the box D,from the outside openings, F. rlfhe ehlorate of potash and many otherproper substances may thus be placed in ljuxtaposition with the ulcersor inilained surfaces of the lungs and throat.

Vhat I claim as iny invention, and desire to secure by Letters Patent,is-

The use and construction of a box to contain medicated powders forrespiration with a revolving fan for mixing them with the air to bebreathed, in the manner substantially as above described.
